(Phys.org)—An airplane's vortex generators, which look like small fins on its surface, improve the plane's aerodynamics similar to the way in which the dimples on a golf ball improve the ball's aerodynamics: by delaying ...
Turbulence makes many people uneasy or downright queasy. And it's given researchers a headache, too. Mathematicians have been trying for a century or more to understand the turbulence that arises when a flow interacts with ...
